MANUAL
POWERSTOP VEHICLE RESTRAINT

The
Manual PowerStop restraint is value
engineered to meet both application and
budget constraints while maximizing
productivity, optimizing efficiency and
improving safety. The PowerStop Series
restraint is designed to comply with
NHTSA 1998 Rear Impact Guard (RIG)
standard.

Mechanical
activation of the PowerStop Series Restraint
is easy. The dock attendant simply lifts up on the release
lever with the operating bar after the truck is parked
against the dock bumpers. The restraint is easily observed
capturing the Rear Impact Guard (RIG). During the
loading process, the spring loaded restraint arm floats
freely with the trailer.

A
uniquely configured restraining arm dramaticallylimits trailer creep to the 50% better than competitors
and substantially reduces the possibility of premature
departure and landing gear collapse.

Effective
Communication

When
combined with Dock Alert communication
system, the PowerStop fosters and extremely safe and
efficient loading dock environment by establishing a
clear line of communication between truck drivers and
dock personnel.

Low
Maintenance Design

A
stationary mount design means less maintenance which
can limit potential damage throughout the life of the
PowerStop. A protective "bellows style" debris guard
prevents debris build up in and around the restraint arm,
reducing house keeping and maintenance requirements.
The PowerStop is quickly and easily stored by pushing
down on the restraint arm assembly with the operating
bar.

The
inside control panel and exterior compact light
package incorporate instinctive red and green signals
which work in opposing modes. A green light outside
guides a backing truck into the dock position while a
red light inside warns the dock attendant that loading/
unloading conditions are not safe. Once the PowerStop
has secured the vehicle, the lights can be witched to
green inside and red outside, informing the truck driver
to not move and indicating a safe condition for the dock
attendant.

Dock
Alert Communication System. Adding the
automatic Dock Alert communication system to the
PowerStop-M establishes a clear line of communication
between truck drivers and dock personnel. During
normal operation the control panel switch is in the On
position. When the restraint arm is in the stored position,
the exterior light will flash green indicating the truck is
clear to approach or depart the dock while the interior
light flashed red warning the dock attendant conditions
are not safe for loading/unloading. Once the restraint has
been activated, and the dock attendant confirms the
restraint arm has engaged the RIG, the Dock Alert will
automatically change light signal conditions. Now the
exterior light flashed red warning the driver not to pull
away, while the interior light flashes green indicating safe
conditions and to proceed with the loading/unloading.
In the By-Pass position, the system will override the
automatic feature providing a flashing red light on the
exterior and a flashing green on the interior.

are
designed to secure a cargo trailers Rear Impact
Guard (RIG) to reduce the likelihood of premature
trailer separation during the loading/unloading process.
The exclusive PowerStop vehicle restraint features a
complete mechanical restraint mechanism, activation
rod and storage bracket, along with communication
signage. An optional Dock Alert Communication
System, including inside control panel and exterior
communication lights, is also available.

CONSTRUCTION:

The
PowerStop-M restraint system is designed to be a
stationary mount, non-impact device, permanently
mounted to loading dock foundation or drive approach.
Restraint shall be preserved in a non-corrosive powder-
coated finish with plated hardware. Restraint arm shall
be protected by a bellows style cover to eliminate the
accumulation of debris. Once activated, the PowerStop-
M extends upward to the RIG. The uniquely designed
dual locking restraint arm minimizes trailer creep,
securing the trailer with over 30,000 lb. (average) of
pull-out force. The PowerStop-M is affordable and
easy to install. It is ideal for all manufacturing,
warehouse and distribution applications.

EXTERIOR
LIGHTS:

Standard
on PowerStop-MML and PowerStop-MAL
restraint packages, low profile, traffic style, incandescent
red and green lights for communication between truck
driver and dock personnel. A set of caution signs warns
truck driver to Back In or Pull Out On Green Light
Only.

OPERATION:

PowerStop-M
- Restraint Only. Once trailer is parked
tight against dock bumpers, the dock attendant inserts
one end of the operating bar under the release lever on
the right hand side of the restraint and lifts up, activating
the restraint. The spring loaded float assembly allows
the restraint arm to move up and down with the RIG
during the loading process. Dock attendant should visually
inspect and confirm that the restraint has traveled vertically
and has engaged the horizontal member of the RIG. The
operating bar can then be returned to its storage bracket.
Dock leveler may be activated and loading/unloading may
begin. When loading/unloading is complete and the dock
leveler is returned to its stored position, the operating bar
is inserted into the top of the slide track on the restraint.
The restraint arm is pushed down until the release lever
locks the restraint arm. Operating bar is returned to its
storage bracket.

ELECTRICAL:

The
PowerStop-M, PowerStop-MML, PowerStop-
MAL vehicle restraint are available as a stand alone unit
or combined electrically with your dock leveler selection.
Electrical requirements for PowerStop-MML and
PowerStop-MAL are 115v single phase installed in a
NEMA 12 enclosure. All electrical control panel
components, connections and wiring are UL listed/
recognized. Please Note: Unless specifically noted on
quotation, all electrical requirements, including mounting
of control box, outside lights and signs, are the
responsibility of others.

PowerStop-MML - PowerStop-M with Manual Dock
Alert Communication System Adding a manual Dock
Alert communication system to the PowerStop-M
establishes a clear line of communication between truck
drivers and dock personnel. At the beginning and end
of a loading cycle, the dock attendant positions the
selector switch on the interior control panel to the Do
Not Service Trailer position. A flashing red light on the
interior panel warns the dock attendant conditions are
not safe for loading/unloading, while a flashing green light
on the exterior wall indicates the truck is cleared to
approach or depart the dock. Once the restraint has
been activated and the dock attendant confirms the
restraint arm has engaged the RIG, the selector switch
should be placed in the Service Trailer position. In this
position the exterior light will flash red warning the driver
not to pull away, while the interior light will be flashing
green indicating safe conditions and to proceed with the
loading/unloading.
